RESUMEN
Puromycin-sensitive aminopeptidase (PSAP) belongs to the M1 family of aminopeptidases, characterized by the N-terminal substrate binding sequence GAMEN, the enzyme activity center HEXXH(X)18E motif, and the C-terminal ERAP-1-like superfamily structural domain. Encoded by the gene NPEPPS located at 17q21.32, PSAP consists of 919 amino acids and is widely distributed throughout the human body, with the highest expression in the brain, followed by the heart and skeletal muscle. It is also found in the liver, renal tubular epithelium, small intestine, large intestine epithelium, and gastric epithelial cells. PSAP primarily relies on its aminopeptidase hydrolytic activity to remove toxic protein aggregates such as Tau, poly Q, and Cu, Zn-superoxide dismutase 1, making it an important factor in the development of diseases such as Alzheimer's disease, Huntington's chorea, and tumors. Existing PSAP inhibitors include bestatin, amastatin, leuhistin, actinonin, and purinomycin, some of which are already available or in clinical trials. This review provides an overview of the structural and biological functions of M1 family aminopeptidases, with a focus on PSAP, to facilitate further research and targeted drug development.
RESUMEN
The biochemical integrity of the brain is necessary to maintain normal function. Oxidative damage is one of the mortal important reasons leading to the destruction of this integrity. The nervous system is enriched in phospholipid and polyunsaturated fatty acids (PUFAs). Due to the nature of high oxygen-consumption and rich lipids, brain is particularly vulnerable to oxidative damages. Phospholipid peroxidation is one of the results of imbalance in oxidation-antioxidant system. Once the antioxidant system is insufficient to resist oxidative damage, membrane phospholipids will be prone to free radical attack. Phospholipid peroxidation leads to a variety of toxic oxidation products, including membrane damage, mitochondrial dysfunction, rapid accumulation of amyloid, etc. Multiple proteins and nucleic acids can be covalently modified by peroxidation products, resulting in the loss of the protein functions, which eventually triggers programmed cell death and general neuroinflammation in brain, and ends up with an increased susceptibility to neurodegenerative diseases. Based on the knowledge of mechanisms of phospholipid peroxidation, this review focuses on the characteristics of phospholipid peroxidation as a key factor in the development of neurodegenerative diseases, in order to provide theoretical basis for targeted intervention of phospholipid peroxidation as a potential strategy to prevent neurodegenerative diseases.
RESUMEN
OBJECTIVE：To systematically evaluat e the efficacy and safety of different regimens in the treatment of refractory Kawasaki disease ，and to provide evidence-based reference for clinical treatment. METHODS ：Retrieved from PubMed ，Embase， Cochrane Library ， CNKI， VIP， Wanfang database ，randomized controlled trials （RCTs）and cohort studies about different therapeutic regimens in the treatment of refractory 84206032。E-mail：liuyingzryy@163.com Kawasaki disease were collected during the inception to March 2021. After selecting the literature and extracting the data ，the quality of RCT was evaluated by modified Jadad scale ，and the quality of cohort st udy was evaluated by NOS scale. Network Meta-analysis was performed by using Stata 16.0 software. RESULTS ：A total of 29 literatures were included ，involving 15 RCTs and 14 cohort studies. A total of 3 112 patients and 12 therapeutic regimens were involved ，including twice IVIG ，twice IVIG+hormone，twice IVIG+ulinastatin ，first IVIG ，first time IVIG+hormone ，first time IVIG+cyclosporine ，first time IVIG+ etanercept，hormone，hormone+ulinastatin，ulinastatin，infliximab and placebo. The results of network Meta-analysis showed that in terms of the incidence of coronary artery injury （CAL），twice IVIG+hormone was significant lower than hormone ，and first time IVIG +etanercept was significant lower than first time IVIG （P＜0.05）. The sorting results of network Meta-analysis showed that area under cumulative ranking curve of CAL incidence in ascending order was hormone ＜ulinastatin＜twice IVIG ＜first time IVIG＜first IVIG+hormone ＜twice IVIG+hormone ＜infliximab＜first time IVIG+cyclosporin ＜first time IVIG+etanercept. In terms of the incidence of ADR ，compared with twice IVIG+ hormone and hormone ，twice IVIG and first time IVIG+etanercept were decreased significantly ；infliximab was significantly lower than hormone （P＜0.05）. The sorting results of network Meta-analysis showed that area under cumulative ranking curve of ADR incidence in ascending order was hormone ＜twice IVIG+hormone ＜first time IVIG+hormone ＜first time IVIG+cyclosporin ＜first time IVIG ＜twice IVIG ＜first time IVIG+etanercept ＜infliximab. In terms of the serum level of CRP ，compared with twice IVIG ，twice IVIG+hormone ，twice IVIG+ulinastatin and hormone were decreased significantly；twice IVIG+hormone was significantly lower than first time IVIG ；twice IVIG+ulinastatin were all significantly lower than twice IVIG+hormone ，hormone，hormone+ulinastatin，first time IVIG ，first time IVIG+hormone and ulinastatin （P＜0.05）. The sorting results of network Meta-analysis showed that area under cumulative ranking curve of serum CRP level in ascending order was first time IVIG ＜first time IVIG+hormone ＜twice IVIG ＜hormone+ulinastatin＜ulinastatin＜infliximab＜hormone＜twice IVIG+hormone＜twice IVIG+ulinastatin. In terms of improving persistent fever duration ，there was no statistical difference between pairwise treatment measures （P＞0.05）. The sorting results of network Meta-analysis showed area under cumulative ranking curve of persistent fever time in ascending order was first time IVIG ＜placebo＜first time IVIG+cyclosporine ＜hormone＜twice IVIG+ hormone＜twice IVIG ＜ulinastatin＜infamliximab. CONCLUSIONS ：The first time IVIG+etanercept has the best effect in reducing the incidence of CAL. Infliximab possesses a relatively low incidence of ADR and the best antipyretic effect. Twice IVIG + ulinastatin has the best anti-inflammatory effect.
RESUMEN
Objective: The aim of this study was to review the published literature and investigate whether sex determining region Y-box 2 (SOX2) is a prognostic factor in head and neck squamous cell carcinoma (HNSCC) by conduct a meta-analysis. Materials and Methods: Trials were identified from the major electronic databases (MEDLINE, EMBASE, and Cochrane Library) using the key words “HNSCC” and “SOX2.” The overall survival (OS), disease-specific survival (DPS), and disease-free survival (DFS) were the primary outcome measures. Results: We identified 371 articles, 9 articles 11 studies with a total number of 1334 cases were eligible for inclusion of this meta-analysis. The results showed that OS (DPS) in low-expression group was higher than that in high-expression group. However, the difference between the two groups was not significant (hazard ratio [HR] = 1.30, 95% confidence interval [95% CI] = [0.88, 1.91]; P = 0.18), and there was great statistical heterogeneity (I2 = 66%, P = 0.002). After subgroup analysis, the HR for OS of the patients with reduced expression of SOX2 was 1.34 (95% CI = [1.04, 1.74], P = 0.03), and the heterogeneity became acceptable (I2 = 32%, P = 0.16). The HR for DFS of the patients with reduced expression of SOX2 was 1.39 (95% CI = [1.00, 1.93]; P = 0.05). Conclusion: The findings of this meta-analysis are indicative of that high SOX2 expression is a negative prognostic factor of HNSCC and exhibit both worse OS and DFS. However, the small sample size available for this systematic review limited the power of this quantitative meta-analysis. It may therefore be too early to place complete confidence in these results
RESUMEN
Metal-organic frameworks (MOFs) are porous crystalline polymers constructed from the coordination reaction between organic ligands and metal ions. Due to their advantages: adjustable periodic pore structure, large specific surface area and easy functional modification, etc., MOFs have been widely used in the fields of gas storage/separation, catalysis, sensing, biological imaging and drug delivery. In recent years, MOFs have shown great potential in disease diagnosis and treatment. This review summarizes the application of MOFs in the fields of bio-sensing, cell imaging, in vivo imaging, drug delivery, etc., discusses the problems and corresponding solutions in the application of MOFs for biomedicine. We hope this review can provide reference for the designing new methods for disease diagnosis and treatment.
